Emerald Crab (Mithraculus sculptus) – Reef-Safe Cleanup Scavenger Emerald Crabs grow up to 2 inches (5 cm) and are semi-aggressive toward other crabs but generally peaceful with fish and invertebrates. They are reef-safe scavengers that help control bubble algae and clean leftover food in established saltwater aquariums. Easy to moderate care, they thrive in tanks with plenty of rockwork and hiding spots, and benefit from extra shells when kept with other crabs. Their diet includes algae, detritus, and supplemental sinking foods as needed.
